China will roll off a new generation of self-developed driverless maglev trains with a designed speed of 200 km per hour in early 2020, according to its lead developer.

Once put into operation, they will be the fastest maglev trains for commercial use in China. CRRC Zhuzhou Locomotive Co.,Ltd. leads the efforts to develop the trains.

Zhou Qinghe, chairman of the company, told reporters Sunday prior to the annual session of the national legislature that new technologies are being used to enable the trains to travel faster and have greater hill climbing power. The latest maglev trains are also equipped with a "powerful brain" to realize safe and reliable autonomous operation.

Zhou, who is also a deputy to the National People's Congress, said the new trains are suitable for inter-city or urban transit between 50 and 200 km in distance. They will also be the world's first maglev trains to run at 200 km per hour, he added.

3月4日消息,2020年初,我国首列商用无人驾驶磁浮3.0版列车将下线,这是我国具有完全自主知识产权的、时速最快的商用无人驾驶磁浮列车。

中车株洲电力机车有限公司董事长周清和在3日接受媒体采访时透露称,磁浮3.0版列车的设计时速在200公里。磁浮3.0版列车的下线,将填补全球该速度等级的磁浮交通系统的空白。

周清和介绍称,相比磁浮1.0版列车和磁浮2.0版列车,磁浮3.0版列车在技术、性能等领域均实现大幅提升,有的甚至可以称为全新突破。

相比之前的两个版本的列车,磁浮3.0版列车在技术上有了全新突破,周清和称。磁浮3.0版列车采用非接触感应供电,取代了原有的接触供电轨,牵引电机由原先的短定子异步电机换成长定子同步电机,而且,牵引逆变器从车身的底部换到了地面电站。

而且,在设计速度上,磁浮3.0版列车也实现了对前面两个版本列车的大幅度赶超。磁浮1.0版列车设计时速100公里,磁浮3.0版列车设计时速160公里,而磁浮3.0版列车设计时速为200公里。

同时,相比磁浮1.0版列车,磁浮3.0版列车的爬坡能力提升了40%。据周清和称,磁浮3.0版列车可以在100米内陡然爬升近4层楼高度,就像"过山车"那样。磁浮3.0版列车的弯道允许通过速度提升超15%,且加速性能良好,平均加速度提升超50%。磁浮3.0版列车的载客量有了进一步的提高,适用于距离在50至200公里之间的城际、市域线路交通。

另外,磁浮3.0版列车配备强大的控制系统。在由地面运行控制系统的控制之下,磁浮3.0版列车可以实现无人驾驶。同时,列车搭载的车地无线通信、大数据分析、在线状态监测等技术,能够实时诊断车辆、供电、轨道等方面的故障,从而实现无人驾驶的安全可靠。

据周清和称,磁浮3.0版列车在下线后,将成为我国自主研发的时速最快的商用无人驾驶磁浮列车。这对于对于今后我国的轨道交通科技创新与产业发展具有重大得到引领示范性意义。
